Grid battery storage supply chain chokepoints

category tradeable chokepoint

How scores are shown

Criticality comes from the trace model and describes the node's dependency importance.

Evidence comes from the canonical Vein Graph: AI assertions, user corrections, and external sources.

Completeness is a data-coverage label based on available summary, evidence, sources, tickers, and chokepoint rationale.

Dynamic claims are capped below 100% and AI-only edges remain labeled as inferred. Model: trace-score-v1.

LFP battery cells & modules90% confidence — EV demand competes for cell output; utility projects slip when cell allocation tightens.

Power conversion systems (PCS)90% confidence — PCS lead times and grid-code certification delay energization dates.

Interconnection queue & transformers90% confidence — Transformer backlogs are the binding constraint on many US BESS COD targets.
